I thought I was cool flying Bimmergeeks Protool! :tumbleweed:

You are the man!

Initial tests of the K3 concentrator (3/E46, Z8 E52, 6/E64) on a 3-series E46:





Yes, it works even on this elder convertible.

Tests of the K4 concentrator (1-series E88, 2-series F23, 6-series F12, Mini R57 & R59) on a 6-series F12:

Not your average simple circuit tester…

 

[RobbiZ4]

Well, that was my initial tool on the E89 roof. :rofl:

Unbelievable what's available right now compared to the first steps.

For the following BMW convertibles the Y3 tool got finished in between (K1..5 are these big blue concentrator boxes):

K1: E89 - Z4 Roadster
K1: E93 - 3-series convertible

K2: F33 - 4-series convertible
K2: F83 - M4 convertible
K2: F91 - M8 convertible
K2: G14 - 8-series convertible

K3: E46 - 3-series convertible
K3: E52 - Z8 Roadster
K3: E64 - 6-series convertible

K4: E88 - 1-series convertible
K4: F23 - 2-series convertible
K4: F12 - 6-series convertible
K4: R57 - Mini convertible
K4: R59 - Mini Roadster

K5: G29 - Z4 Roadster
K5: G23 - 4-series convertible
K5: I15 - i8 Roadster
K5: F57 - Mini Cabrio

In between, also the 5th concentrator box got completed as well as tested successfully.

The latest test of the K5 BlueBox was on a new Z4 G29:

Just Robbi's inventive way of bumping his thread oke:

 

[Prodjay10]

What would the this run?

 

[enuff_zed]

What would the this run?

???
It doesn't 'run' anything per se, it's a fiendishly clever box of tricks, developed by Robbi (and his minions :wink: ) to diagnose any issue with the roof on the E89 by monitoring the sequences of every switch, relay etc.
Knowing the Germans' propensity for engineering perfection I suspect it will also make you a coffee while you wait.

 

[RobbiZ4]

...I suspect it will also make you a coffee while you wait.

... and finally it's able to clean up the dishes. :rofl:

Robbi, echoing others, this is brilliant work indeed. Wunderbar!

I’ve been reading your advices here and elsewhere. You say all roofs eventually fail. Would you advise to preemptively replace all parts that normally fail? How long would them last? Or wait until the failures pop up?

You’ve also offered to travel. (California is beautiful this time of the year.) It’d be great to understand how much that would cost.

Thanks.

Marc.

This thread is regarding the Y3 Diagnostic System and should be kept clean.

As of today, I've completed the next concentrator box (BlueBox K2) for another couple of BMW convertibles:

Interesting story regarding the usage of wire "harness" or "loom"

Why are Wiring Harnesses Sometimes Called "Looms”? - InterConnect Wiring

A wiring loom, also known as a harness, wire harness, cable assembly, wiring assembly or wiring harness, is an assembly of wires which transmit signals or electrical power.

www.interconnect-wiring.com

"The term “loom” was commonly used in the aerospace and automotive industry half a century ago. A wiring loom, also known as a harness, wire harness, cable assembly, wiring assembly or wiring harness, is an assembly of wires which transmit signals or electrical power. The wire looms are bound together by braiding, straps, cable ties, cable lacing, sleeves, electrical tape, conduit, a weave of extruded string, or a combination thereof. So, the word wiring harness and wire loom are interchangeable..."

You always have to consider that a sensor can not only fail completely, but can also change its switching state with a delay. The CTM always checks the timing as well.

In the following chart, you'll see an unexpected delay of about 1-2 seconds.


Time to replace both(!) microswitches.
